'NUT-LOCK.-

SPECIFICATION forming part of Letters Patent No. 664,964, dated mini- 1, 1991,.

To all whom it may concern:

-Be it known that I, J AMES M. KLINE, a citisen of thellnited States, residing at- Beaverclass in which a pin is employed to lock the nut on the bolt; and it consists in the combination and arrangement of parts hereinafter fully described and claime In the drawings, Figure 1 is"a perspective V view of a nut-lock constructed in accordance with the present invention.

qck s-pin.

v, 1 designates 'azr'erdi ary'bolt having a longitudinal-groove 2' extending throughout the screw-threaded portion thereof. Screwed to the bolt in thensnal-manner is a nut 3,1that 6 between the outer end is provided with a smooth radial opening 4, the inner end-of which opens into the screwthreaded hereof the nut and the outer end of which extends-to one of the angles or cormore ofthe nutat a point adjacent to the outer facethereof, thereby forming a tongue of said opening and the face of the nut.

To look the nut after it has been properly set, with-the, opening 4 registering with the groove-2, a. suitable smooth looking-pin 5 is inserted "intothe opening, so that the inner end of the pin may be received within the groove. Tosecure the pin in engagement thin'tongue 6, formed by that portion of the nut at the corner or angle thereof which is between the outer side of the opening and the outer face of-the nut, is struck slightly with a punch or other suitable implement to bend the tongue inward, andthereby form an 01fset which overhangs and engages the outer end of the pin. It will of course be, understood that it requires but a slight blow to bend the tongue'overthe pin sufiiciently to prevent accidental displacement thereof, whereby the tongue portion of the nut is displaced or bent but a trifle, and it may be readily bent back and straightened into its normal position by a slight blow'from a punch to clear the opening and enable the pin to beremoved to free the nut. llhu's it .will be apparent that the Appllcstionfiledl'ebmsry 28,1900. sums. 0,815. (somatic lo'oliing-pin may be applied and removed without damaging any parts of the device, and

thereby the bolt, the nut, and-the pin may be used a number of times.

' Although but one groove has been shown in the drawings, it will of course beunderstood that a pluralityofsuch grooves maybe termed in the bolt, and an-opening maybe-"formed for'e'ach corner of the nut,"so that afmuch .firmeradjustment off the latter may be had.

- Witnesses:

Although a substantially;cylindrical locking-pin has been shown in' thedi awingajt will of course .be understoodfthatan" angular pin may be employed with equal'eflect:

Having thus deslcoibed' my invention, I claim-- f 1. In combination with a bolt having a longitudinal groove in oneside, a nut, having an opening communicating at itsinner'endwith said groove, said'openingextendingtoone of the cornersor anglesof the not at a point near one facethereof, whereby a tongue is formed between said opening and the .face of the 'nut, a pin in said opening and having its inner. end engaged in said groove to prevent the nut, from turning, the outer end of the said tongue of the nut being adapted to be 'bentto form an olfset overhanging and engaging the outer end of said pin, to secure the" latter from disengagement with thelsaid groove, said tongue being adapted to be straightened-out toreleaseisaid pin, substantially as described.

2. As a new article of manufacture, a nut having an opening, adapted to receive a look ing pin, said opening extending from the threaded bolt-hole to one of the corners or angles ofthe nut at a point near one face thereof,

whereby a tongue is formed between said opening'and the face of the nut, the said-- tongue being adapted to be bent to form an ofis'et in said opening and to be straightened out to clear said opening, whereby a locking-, pin may be readily secured in and released from said opening, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
